It’s been well documented by now that TUF: Brazil Season 3 coaches Wanderlei Silva and Chael Sonnen were involved in some kind of physical altercation while filming the show, and a new sneak preview for the season has given at a glimpse at the moments leading up to it.

The footage shows an aggravated Silva getting up close and personal with Sonnen, shouting and pointing aggressively at him. As things escalate Silva seems to be goading him to fight right there and then, but Sonnen seems to be trying to calm him down, telling his rival to “stop it.”

Silva then claps his hands in Sonnen’s face which leads to Sonnen shoving him away. Silva responds by trying to throw a punch as Sonnen ducks under reaching for a double-leg takedown and that’s where the video cuts out.

The season is set to premiere in March on the UFC’s new ‘Fight Pass’ subscription service.
